In electronics, a bleeder resistor, bleeder load, leakage resistor, capacitor discharge resistor or safety discharge resistor is a resistor connected in parallel with the output of a high-voltage power supply circuit for the purpose of discharging the electric charge stored in the power supply's filter capacitors when the equipment is turned off, for safety reasons.
Structurally, capacitors consist of electrodes separated by a dielectric, connecting leads, and housing; deterioration of any of these may cause parameter shifts or failure. Shorted failures and leakage due to increase of parallel parasitic resistance are the most common failure modes of capacitors, followed by open failures.
A glitch (circled in red) occurring during circuit operation. Glitch removal is the elimination of glitches—unnecessary signal transitions without functionality—from electronic circuits.
Failed aluminium electrolytic capacitors with open vents in the top of the can, and visible dried electrolyte residue (reddish-brown color) The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers, [1] [2] due to faulty electrolyte composition that ...
A discharged or partially charged capacitor appears as a short circuit to the source when the source voltage is higher than the potential of the capacitor. A fully discharged capacitor will take approximately 5 RC time periods to fully charge; during the charging period, instantaneous current can exceed steady-state current by a substantial ...
The current that flows through these capacitors is due to the capacitors' impedance at power line frequencies. [6] [7] Some amount of leakage current is generally considered acceptable, however excessive leakage current, exceeding 30 mA, can create a hazard for users of the equipment. In some applications, e.g. medical devices with patient ...
A father killed his 3-year-old son by locking him in a washing machine and letting it run for five minutes. The father was allegedly punishing his son for bad behavior. The father was allegedly ...
A Beko washing machine; modern household washing machines start at 1 kg (2 lb) capacity, designed for smaller households, and span to 24 kg (53 lb) load capacity. In 2003, Maytag introduced their top-loading Neptune TL FAV6800A and TL FAV9800A washers. Instead of an agitator, the machine had two washplates, perpendicular to each other and at a ...
